Relay Automotive Procurement Notes

Verify that the specific part number matches the required 24 VDC coil specification and 40A rating. Confirm the package type aligns with chassis mounting requirements. Ensure compliance with RoHS standards if applicable to your assembly. Cross-reference the datasheet for terminal pinout accuracy before integration into the final design.

Relay Automotive Selection Notes

Select this relay when a high-current 40A switching capability is required within an automotive context. The 24 VDC coil voltage must match the vehicle's electrical system architecture. Consider the sealed design for applications exposed to harsh environmental conditions where standard open relays might fail due to corrosion or moisture ingress.

Relay Automotive Part Context

This component belongs to the AZ986 series of automotive relays from American Zettler. The series is engineered to meet ISO standards for automotive electrical components. Variations within the series typically differ by coil voltage and contact configuration, while maintaining consistent mechanical dimensions and mounting styles for interchangeability.

Relay Automotive Replacement Considerations

Direct substitutes include other 40A 280-ISO compatible relays with identical pinouts. Verify coil voltage compatibility to prevent operational failure. Ensure the replacement maintains the SPDT contact form and sealed housing characteristics required for the specific application environment.
